x11-synaptics 1.3.0

I happen to unintentionally trigger "drag on tap" too often so I tried to disable it. But it also disabled double tapping completely (and I have feeling that single tap became "slower" too). This was the only change:

    Don't release the button on TS_3 if TapAndDrag is disabled (#31854)
